Velu Nachiyar (1730-1796) was the Tamil queen of Sivaganga — the first Indian monarch to wage and win war against the British East India Company, in 1780, decades before the Sepoy Mutiny of 1857. After her husband's killing by the British, she trained an all-female regiment named Udaiyaal and is credited with deploying the world's first known suicide bombing through her commander Kuyili (who walked into the British powder magazine doused in ghee).
Honored on a 2008 Indian postage stamp.
Velu Nachiyar does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Velu Nachiyar reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
